CENTRIFUGAL MACHINE.

SPECIFICATION forming part of `Letters Patent No. 650,958, dated .T une 5, 1900.

' Application filed September '7, 1899. Serial No. 729,702. (No model.)

To all whom it mctycoucewz:

Be it known that I, CARL STUTE, manufacturer, a subject of the Emperor of Germany, residing at Ricklingen, near Hanover, Germany, have invented certain new and useful Improvements in Centrifugal Machines, of which the following is a specification.

This invention relates to a centrifugal machine in which the drum may be easily and effectively emptied frombelow, so that especially linens, dresses, and other textiles may be removed without being injured.

In the accompanying drawings, Figure l is a vertical section of the upper drum; Fig. 2, a similar section through the machine complete; Fig. 3, a vertical section through a modification of the drum, and Fig. 4. a similar section through the modified machine complete.

The letter B represents an upper perforated revolving drum which is provided with the spring-actuated hooks or catches e, pivoted to its sides. The upper ends oi' the hooks e are perforated, as at e', for the attachment of the suspending ropes or chains E, while their lower ends project below the lower open end of the drum. The drum B when lowered is adapted to rest upon a bottom C, to which it will be connected by the hooks e. y

The bottom C is provided with a central hub C', that receives the upper end of the vertical driving-shaft D. When the drum is raised, the hooks e will by the strain on chains E be automatically opened ;to release the bottom C, and thus the contents of the drum will be freely discharged. When the drum is lowered upon the bottom and the suspending-chains slackened and uncoupled from the eyes c', the hooks will again automatically rengage the bottom.

In Figs. 3 and'4. the upper drum B lits into a lower drum A, provided with' the bottom C2 and revolu'bly mounted upon the drivingshaft D'. In thismodication the drums B A are connected by the catches or bolts j", provided with the eyes f for the attachment of the suspending-chains E. The bolts slide in keepers secured to the upper drum and engage suitable seats of the lower drum; Then the upper drum is raised, the tension on the chains E will cause the bolts to move inward and to thus become disengaged from the drum A. In this way the drum B is liberated and its contents will be freely discharged.

What I claim isl. In a centrifugal machine, the combina- -tion of a drum having an open lower end, with a bottom, catches secured to the drum and adapted to engage the bottom, and suspendingchains adapted Yto be secured to the catches, all being so constructed that the strain on the suspending-chains will cause the catches to open, substantially as specified.

2. In a centrifugal machine, the combination of a drum having an open lower end, with a bottom having a hub, a driving-shaft engaging the hub, catches secured to the drum and adapted to engage the bottom, and

suspending-chains adapted to be vsecured to the catches, substantially as specified.

3; In a centrifugal machine, the combination of a drum having an open lower end, with a bottom having a hub, a driving-shaft en gaging the hub,and spring-actuated catches projecting below the lower edge of the drum and adapted to engage the bottom, substantially as speciiied.
